英文摘要: We theoretically investigate four types of dynamical instability, in particular the periodic and oscillatory type I-O, in an antiferromagnetic spin-1 Bose-Einstein condensate in a nonzero magnetic field, by employing the coupled-mode theory and numerical method. This is in sharp contrast to the dynamical stability of the same system in zero field. Remarkably, a pattern transition from a periodic dynamical instability I-O to a uniform one IIIO occurs at a critical magnetic field. All four types of dynamical instability and the pattern transition are ready to be detected in Na-23 condensates within the availability of the current experimental techniques.
